Description
Technical Field
The utility model belongs to the technical field of injection mold, especially, relate to a can tear sheath pipe injection mold.
Background
The tearable sheath is a medical apparatus which has a dilation function and can help a catheter enter a blood vessel, and mainly comprises a cannula sheath and a dilator with a tip, wherein the cannula sheath comprises a tearable tube body and a tearable seat. When the catheter is used, the tearable sheath is pushed into a vein vessel along the guide wire in a percutaneous mode, then the intubation sheath is left in the vessel, the guide wire and the dilator are withdrawn, the intubation sheath forms a channel between the outside and the vein vessel in vivo at the moment, the catheter can be smoothly and smoothly placed into the vessel along the intubation sheath, finally, the tearable joint of the intubation sheath is broken off, and the tearable catheter body can be smoothly torn into two halves and is completely withdrawn from the body. The tearable sheath is particularly suitable for some catheters which are softer, have closed head ends and the like and can not be smoothly placed into the blood vessel along the guide wire, thereby greatly improving the success rate of placing the catheter.
Traditional mode that can tear sheath pipe adopts manual assembly to process usually in process of production, and this kind of mode need consume a large amount of manpowers, very big increase workman's intensity of labour, and the inefficiency of manual assembly simultaneously, the product of formation is not integrated into one piece, and product quality is relatively poor.
